PANE.

Speciiication of Letters Patent.

Application led January 2, 1915. Serial No. 208.

To all 'whom t may concern:

Be it known that I,.LILLIAN M. LEA, a citizen of the United States, anda resident of Ramsey, in the county of Bergen and State of New Jersey,have invented a new and Improved Pane, of which the following is a full,clear, and exact description.

An object of the invention is to provide a new and improved pane for use1nwindows, glass doors, partltions and other struc-` tures, and arrangedto permit looking through the pane from one side and to prevent seeingthrough the same from the other side.

A further object is to provide apanewhich is exceedingly strong anddurable and has a lace curtain effect. y

In order to accomplish the desired result use is made of a sheet ofglass in which is embedded an open mesh fabric such as wire netting,covered wholly or in part with a ireproof, loose, iiu'y material suchasasbestosfibers, arranged according to a predetermined design such asthat of a lace curtain to produce a lace curtain effect..

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all'theviews.

Figure 1 1s a face view of the pane with a portion of the covering layerof glass removed; Fig. 2 is an enlarged face view of the open meshfabric covered with loose material; and Fig. 3 is an enlarged crosssection of the pane.

The pane consists essentially of a'sheet of glass formed of two layers Aand B, between which is embedded an open mesh fabric C, preferably wirenetting, covered in whole or in part along its members with a loose,fluify material D, preferably fireproof, such, for instance, as asbestosfibers. `he loose material D is arranged according to a predetermineddesign, such, for instance, as that of a lace curtain, as indicated inFig. 1. In practice, the layer A is the main or outer layer while thelayer B is the covering or inner layer and is very thin in comparisonwith the main layer A. By this arrangement the wire netting C and itsloose material D is located near one face of the sheet of glass, thatis, near the inner face of the sheet, in case the sheet is used as awindow pane, for instance, B the arrangement deiatena June la, reis. c

doti

scribed, a person msi e of a room can rea ily look through the pane ofglass to the outside, but a person standin on the outsidecannot lookthrough the wlndow pane Into the room. To the person on the outside the'loose material presents a lace curtain eiect.

In the manufacture of the pane, a batch of molten glass is dumped ontoa. table to approxlmately the thickness of the layer A and then the wirenetting C with its coverr lng mater1al D 1s placed on top of this glass,

after which another layer of molten glass 1s placed on. top' of the wirenetting and is rolleddown by the use of a suitable roller so that theglass passes through the meshes or interstices of the wire netting C andits covering to unite with the glass of the first bath, that is thelayer A. The outer surface of the covering layer B is preferably leftundulating or rough, thus aiding the covermg materlal and the wirenettlng in preventing a person from looking through a pane from theoutside.

A pane constructed in the manner described can be readily used inwindows, glass doors, partitions and other structures especially as thepane lis reinforced by wire netting while the covering material producesa lace curtain effect.

Having thus described my invention, I

claim as new and desire to secure by Letters' Patent:
